陆丰海洋基地码头工程防波堤平面布置

Plane layout of breakwater for Lufeng marine base wharf project

为保障泊稳条件、减轻工程对周边岸线的影响、合理降低工程投资,对陆丰海洋基地码头工程防波堤平面布置进行研究。结合波浪和潮流观测资料、遥感影像历史资料,运用波浪、潮流泥沙及岸滩演变数值模拟手段,分析陆丰海洋基地所在地水文特性,厘清不同防波堤平面布置方案下泊稳条件、波浪荷载、流场变化、泥沙运动及岸滩演变特点,探讨工程平面布置方案的优劣。经对比分析,考虑预留更多的扩建空间及分期建设的便利性,建议采用东北开口方案,暂不延长防波堤,并对受影响岸段辅以相应的岸滩整治措施。

To guarantee the berthing conditions,mitigate the impact of engineering on the surrounding shoreline,and reasonably reduce the engineering investment,we study the layout of breakwater in Lufeng marine base wharf project. Based on wave and tidal current observation data and historical data of remote sensing images,and carrying out the numerical simulation of wave,tidal current,sediment and beach evolution,we analyze the hydrological characteristics of Lufeng marine based,clarify the berthing stability conditions, wave loads, flow field changes,sediment movement and shore evolution characteristics under different breakwater layout schemes,and discuss the advantages and disadvantages of them. According to the comparative analysis,and considering the convenience of reserving more expansion space and phased construction,we suggest to adopt the northeast opening scheme and do not extend the breakwater currntly,and supplement the affected bank with corresponding beach regulation measures.
